From fe55ea85939efcbf0e6baa234f0d70acb79e7b58 Mon Sep 17 00:00:00 2001 From: Pingfan Liu Date: Tue, 16 Dec 2025 09:48:51 +0800 Subject: kernel/kexec: change the prototype of kimage_map_segment() The kexec segment index will be required to extract the corresponding information for that segment in kimage_map_segment(). Additionally, kexec_segment already holds the kexec relocation destination address and size. Therefore, the prototype of kimage_map_segment() can be changed.
